My Dell C840 got bit by the 8.19 bogomips too, and I found some MORE damage
caused by this.

2.6.2-rc1-mm1 with X86_PM_TIMER finds my Ethernet cards just fine.

2.6.2-rc1-mm2, the 3c59x driver fails to find the MAC address for the cards:
(the Xircom pcmcia (eth2 below) and Orinoco wireless (eth3) drivers *do* find
their cards):

(eth0 is the onboard ethernet, eth1 was the one on the docking station). lspci says:

0000:02:00.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78)

Building without X86_PM_TIMER the 3c905 is found:

% ip link show

(Am roaming and not docked, which is why the dock 3c905 isn't listed)
